Choosing Trees for Larger Public Landscapes (and your yard!)

Still one of my favorite Oak photos. This one take in the late afternoon beneath a canopy of Interior Live Oak (I think) at Shiloh Ranch Park, last March.

A friend recently asked me if I had some favorite trees that I would recommend for planting on school landscapes, that would be like asking if I had favorite park trees, no I don’t…and I don’t have a list of proven performers either. A planting site being located at a school, only tells me something about the uses/abuses one can likely expect on a site, and nothing more. When we choose plants we need to be paying attention to a lot more than that. Many people are intimidated when it comes to choosing trees, there are so many and potentially, they live so long, growing from year to year…all of this tends to magnify the ‘weight’ of our decision.  People often look for short cuts because there are so many things to keep in mind when choosing. There are two major questions that need consideration first, the site conditions and design, what will the tree have to put up with and what do you expect? Continue reading →

Tri-Met’s Orange Line Landscapes: Bybee Stop to Oak Grove

Part 2 of the Orange Line series

Looking south from the top of the stairs at the Bybee Stop. This is pretty much the same view as looking north with respect to the landscape.

Looking south from the top of the stairs at the Bybee Stop. This is pretty much the same view as looking north with respect to the landscape.  BNSF’s tracks lie to the left, the east.  The railroads have their own ‘landscape’ maintenance standards set primarily for safety reasons.  Within so many feet of their tracks they have a zero tolerance for plant growth and use sterilants.  There is also a zone within which the will ‘brush back’ trees and shrubs to keep site lines open.  Metro will have its own standard.  The two side by side show their combined effect.  Also, typically railroads do not fence off their tracks making clear sight lines a more pressing safety concern.  Trimet has fenced off the tracks from casual pedestrian ‘conflicts’.  Fencelines are problematic for maintenance unless ‘dead zones’ are expanded to include both sides.

Heading south of the Harold St. overpass the Orange Line leaves the most urbanized portion of its route, or at least its most densely populated stretch.  Traveling south to the Bybee, the Tacoma/Sellwood and then the Milwaukie stops, the line run alongside the BNSF tracks and there is very little ‘landscaping’ of the corridor.  The railroads contract out maintenance of their thousands of miles of tracks. (For a brief look into their approach check this link.) Continue reading →
